To allwhomz'tma concern.

Be it known t at I, AARON S. Nionons, a citizen of the United States, and a, resident of the city, county, and State of New York, have invented a new and useful Improvement in Spraying Apparatus, of which the following is a full, clear, and exact description.

My invention relates to improvements in apparatus designed to throw liquid into a spray, and is more especially desi ned for apparatus of this kind 1n which a su stantial volume of spray is desired. An important use of apparatus such as described is in connection with air washing devices, but the spraying device can be used for other urposes. My improvements apply to machines or apparatus of the general character disclosed in Letters Patent of the United States No. 1,296,315, dated March 4th, 1918, for improvements in air washing apparatus. In apparatus of this kind rotary disksare used which dip slightly into the liquld to be sprayed, and then pick up and break up the liquid into a spray. Heretofore it has been the practice in such apparatus to have parallel disks mounted on a shaft and arranged at right angles to the shaft so as to di into the water or liquidto be sprayed. have found by experiments, however, that if the disks are pitched at an inclination to the shaft, I get a much better effect, as in this case the spray picked up, by a particular disk is thrown violently against the adjacent disk and is thus broken up into very fine particles. Even though the edges of the disks may 'be constructed to pick up and break up the liquid, I still get an appreciably better effect if the disks are inclined, for the reasons stated above. In carrying out this idea I have had the best results by arranging the disks at an inclination to the shaft, and in substantially arallel relation, but they can be arranged at opposite inclinations, and at various inclinations with respect to each other, without affecting the invention. The disks also can be secured to their shaft in any convenient way, and I have shown a suitable means of attachment.

Reference is to'be had to the accompanying drawings forming a part of this specification, in which simllar reference characters indicate corresponding parts in all the views. Figure 1 is a sectional elevation showing the general arrangement of disks, disk chamber, and liquid.

Fig. 2 is an enlarged sectional view showlng a convenient means of fastening the disks to their shaft, the middle portions of the disks only being shown.

F 1g. 3 is a side or edge view of a washer which can be used to glve the disks the desired pitch. F g. 4 is a cross section of the washer.

Fig. 5 is an end view of a part of the collar which carries one of the disks, and F1g. 6 is a view similar to Fig. 2 but showing a modified arrangement of the disks.

Apparatus of this kind is generally arranged with a shaft 10 turning in a chamber or box 11 above a body of liquid 13 'WlllCh is sometimes heated by pipes 14, but whether or not the liquid is heated has nothlng to do with this invention. The disks 12 are generally formed with peculiarly constructed edges, as for instance in the patent hereinabove cited, so as to pick up the water readily, but my invention has no 1 reference to the conformation of the edges,

but rather to the arrangement and pitch of the disks by which I et a new and better result. Asshown in ig. 2 the disks are preferably substantiall inclination to the sha t 10. My invention does not lie in the manner in which the disks are attached to their shaft, but I have shown a convenient means so as to make it clear that the invention can be carried into effect. As illustrated each disk is mounted on a collar 13 which is attached to the parallel but at an shaft 12, and this collar has a tapering hub 14 which is slit at intervals longitudmally as at 15 (see Fig. 3) so as to make spring segments. The disk fits on the hub and against one side of the collar 13 and" a tapering nut 16 screws on the part 1 1 of the collar and thus fastens the disk in' place, and

at the same time clamps the segments of the pitch, washers 17 may be used which out of parallel but still inclined with respect to the shaft 10, so as to get the effect desired .that is to sa when the disks are inclined they not 0 y appear to pick up the water better and break it up into fine particles, but they also throw it laterally against the adjacent disk and make the spray still finer. 1 p

In Figs. 2 and 3 for the sake of clearness only the middle portions of the disks are shown but it will be seen that if they were carried out to their full diameter the edges would be nearly to ether, and it will be readily understood ow the above action takes place.

Where the wed e shaped washers 17 are used, it is advisa le to have the flange of the collar 13 rovided with pins 18 which extend throug corresponding holes 19 in the washers and in the disks 12, and this prevents the washers from slipping around so as to get the thick sides opposite each other.

Attention is called to the fact that in order to have the apparatus work successfully there must be at least a lurality of disks. This a paratus is used when it is necessary to pro uce a very fine spra which is practically a mist, in 'order t at air may be washed and the nicer operations of removing dirt and impurities perfectly carried out. If a single disk were usedit would not have the desired result, but when a plurality are used, and they are placed at an inclinat1on to their axis and arranged side by side,-

it will" be seen that the jets and particles of water which are picked up b one disk impinge against the next disk, an arethere- I by broken up, and furthermore the parti-v cles raised. by the several disks impinge against eachother, and the result is an exceedingly fine spray. Thisapparatus has and results in a much finer spray than has heretofore been produced.

I claim inclinations.
